ABSTRACT

A TERTIARY AMINE GROUP SUBSTITUTED ETHYL CELLULOSE, PREFERABLY DIETHYLAMINOETHYL ETHYL CELLULOSE AS A BINDER. tHE TERTIARY AMINE SUBSTITUTED ETHYL CELLULOSE DISSOLVES IN A SLURRY OF TOBACCO FINES ACIDIFIED TO A SLIGHTLY ACID PH. UPON DRYING OF THE SLURRY AND REMOVAL OF THE ACID, THE DIETHYLAMINOETHYL ETHYL CELLULOSE FORMS A BINDER FOR THE TOBACCO WHICH IS INSOLUBLE AND RESISTANT TO SWELLING IN WATER. WHEN THE TOBACCO PRODUCT IS SMOKED, THE BINDER DOES NOT DISSOLVE OR BECOME SLIMY IN THE USER&#39;&#39;S MOUTH.

A24b 3/14 U.S. Cl. 131-17 A No Drawing. 4 Pages Specification Reconstituted tobacco compositions are prepared using a tertiary amine group substituted ethyl cellulose, prefcrably diethylaminoethyl ethyl cellulose as a binder. The tertiary amine substituted ethyl cellulose dissolves in a slurry of tobacco fines acidified to a slightly acid pH. Upon drying of the slurry and removal of the acid, the diethylaminoethyl ethyl cellulose forms a binder for the tobacco which is insoluble and resistant to swelling in Water.
